Alternative to Winterizing

I live in an area where it might be 60 one day and 28 the next. I don't like the idea of winterizing one day and reversing the procedure the next day. And so on. Is there an alternative to this process such as heating one's motor home with a small (or large) heater plugged into house power? I don't have access to an RV garage or storage area. Run the heater on cold nights - turn it off when the day get warm?

    this is what i have been doing the last 5 years. i bought a cheap regulator and fittings a Lowe's. i hook my air compressor to my city water port.

    quick, easy, safe
  • I winterize by moving to a warmer climate when cold weather arrives. If this solution will not work for you then winterize until warmer weather arrives. It's not worth taking the chance that something will freeze. After all there is no guarantee that the 28 degree day will be followed by a 60 degree day. It is just as likely the second day will also be 28 degrees.
  • I would tend to just blow out the lines. Then use when needed.
    Otherwise yes you can run the furnace but it will cost you.
    I would not rely completely on a portable electric heater.
  • Hi,

    It is possible to heat an RV electrically. Replace the return air grill on the furnace with a window fan. Add a mechanical thermostat so the fan will cycle when the cavity gets cold. Use a couple of 500 to 800 watt heaters. I prefer oil filled ones myself as they are unlikely to be a fire hazard.



  • Sometime ago an RVer suggested putting a couple of gallons of white wine into the Freshwater Tank and not worry about the 28 degrees. It makes taking showers and brushing teeth more fun also!
    I have the wine but haven't dumped it into the tank yet.

  • I agree with Genecop.
    When you use an electric heater it does keep the interior of the coach warm, but the tanks are usually below the floor and some units have a heat duct that blows warm air into the tank location.
    Also your water tank is insulated to the inside of your coach and also will not get the benefit of the electric heater.
    I have actually on those iffy nights left the furnace on low and the coach plugged in. Aslo left the hot water tank on.
    Better safe than sorry
  • Not really, if you plug in a portable heater you will not help warm the tanks the way most RV heating systems are designed......you are asking for trouble if it goes down to 28 with water in your lines, tanks, drains, etc....
